The domesticated carmine cochineal Dactylopius coccus (scale insect) has commercial value and has been used for more than 500 years for natural red pigment production. Besides the domesticated cochineal, other wild Dactylopius species such as Dactylopius opuntiae are found in the Americas, all feeding on nutrient poor sap from native cacti. To compensate nutritional deficiencies, many insects h...

C.I. Natural Red 4 dye, also known as carmine or cochineal, was adsorbed onto the surface of spongin-based fibrous skeleton of Hippospongia communis marine demosponge for the first time. The influence of the initial concentration of dye, the contact time, and the pH of the solution on the adsorption process was investigated. The results presented here confirm the effectiveness of the proposed m...

AIM To validate high definition endoscopes with Fujinon intelligent chromoendoscopy (FICE) in colonoscopy. METHODS The image quality of normal white light endoscopy (WLE), that of the 10 available FICE filters and that of a gold standard (0.2% indigo carmine dye) were compared. RESULTS FICE-filter 4 [red, green, and blue (RGB) wavelengths of 520, 500, and 405 nm, respectively] provided the ...

a simple special protocol using semichon’s acetic carmine stain was applied for examination of muscles of some small mammals, naturally infected with sarcocystis spp. using this method, infected muscles fibers with sarcocystis could easily be differentiated from muscle tissues. this method can be applied for screening of infected muscles with sarcocystis cysts on large number of samples for epi...

In this study a method for evaluating phenotypic sex in Nile tilapia was validated. A technique that uses aceto-carmine squash mounts to stain the entire gonadal tissue for microscopic examination (Method 2squash mounts) was compared with a technique based on traditional histology. Approximately 2600 Nile tilapia fry weighing and measuring, respectively, between 0.25-2.50g and 26-53mm, aged 35 ...

AIMS The purpose of this study was to compare the diagnostic performance of an immunoassay for placental alpha microglobulin-1 (PAMG-1) in vaginal fluid with the intra-amniotic instillation of indigo carmine for the diagnosis of membrane rupture in patients with an equivocal status. METHODS A prospective multi-site study was performed involving women reporting signs, symptoms, or complaints s...

To obtain more information about Paragonimus species prevalent in Manipur, India, hundreds of freshwater crabs, Potamiscus manipurensis, were captured from mountain streams in the Motbung Mountains in Senapati District, from December 1997 to January 1998. Crab extracts were prepared by digestion, differential filtration, and sedimentation. The filtered sediments were critically examined under a...

Two sensitive spectrophotometric methods are presented for the assay of pantoprazole sodium sesqui hydrate (PNT) in bulk drug and in formulations using Nbromosuccinimide (NBS) and two dyes, methyl orange and indigo carmine, as reagents. The methods involve the addition of a known excess of NBS to PNT in acid medium, followed by determination of unreacted oxidant by reacting with a fixed amount ...
